Practical Exploration Of Improving Students' Modeling Ability In Physics Revision Of Senior Three

Improving the quality of physics review teaching in grade three of senior middleschool has always been an important topic for physics teachers to explore and study The "2008 Plan" of the college entrance examination which carried out under the newcurriculum reform in Jiangsu province has clearly defined what abilities andconceptions should be examined in college entrance examination papers.In the past10 years,the content of the test questions has been attached importance to theconnection with modern production and life,and is related to the latest physical andtechnological achievements and hot issues.It puts forward higher requirements forstudents' comprehension and modeling ability to solve this kind of situationalquestions.The following study was based on extensive reading of literature on the trainingof college entrance examination and physical modeling ability.First of all,atheoretical exploration is made on the training of students' modeling ability in physicsreview teaching;Second,an investigation and analysis of the depth and breadth ofphysical model examination of the 10 physical college entrance examination papers in2008-2017 years is carried out,find that the requirements of the college entrance examination for the general level model,the higher level model and the highest levelmodel are generally stable,the proportion is about 3:5:2.Third,a physical simulationtest for my students was carried out,and the results of examination were analyzed,itis concluded that students' mastery of general models is not yet in place,for higherlevel models,they are not good at comprehensive analysis,for highest level models,they can't model themselves.Fourth,the strategy of cultivating students' modelingability in grade three of senior high school physics review teaching is discussed:Guide students to straighten up the main physics model in high school,strengtheningthe students' modeling process,using variable types of sample to help students build a clear model,strengthen the model construction,guide and experience and strengthenthe training of the original problem modeling ability.Finally,the specific practice andpractice cases are analyzed.
